The hepatocyte primary culture (HPC)/DNA repair test was developed using hepatocytes isolated from male F-344 rats. A number of genetic polymorphisms have been shown to occur in inbred strains of rats, which may lead to variation in biotransformation of xenobiotics resulting in differences in susceptibility to genotoxins. The effect of the strain utilized as a source of hepatocytes was investigated with female Lewis, F-344, and DA rats. Variation was observed when hepatocytes from the three strains were exposed to aflatoxin B{sub 1} (AFB{sub 1}). No clearcut strain differences were seen when cells were exposed to diethylnitrosamine (DEN) or 2-acetylaminofluorene. These results demonstrate that both the strain and the sex of the animal used as a source of hepatocytes can affect the HPC/DNA repair test.
